i've got some questions about QnQ:
1 command 'set dot1q-all-tagged enable' do you think can create disruption in traffic?
2 is jumbo frames enough 1504 Bytes?
3 how can i assign a VLAN to a tunnel?
i'll add a attachment for clarify situation, vlan 2-3-4-5-6 must not see other vlan on switch A-B-C-D and switch A-B-C-D must see each other VLAN 9-10-11-12.
can i transport also vlan 8-9-10-11 in dot1q mode (i need those VLAN in devices A-B-C-D) or i need to encapsulate in Q-inQ? Link intra switches (trunk all) needs sono change (jumbo frames)? if link 1 died is trunk all able to transpost all the stuffs?
Thanks a lot for an answer, and thanks anyway for attention :)
